ARTE'IE PERRIN; GE'NEW LISKEABlD, ONTAERO CAfNADA:

TABLE LOCK.

Application filed May 16,

T all w ?mm it may concern Be it known that I, `An'rirnn PERRIN, a subject of the King of Great Britain, and resident of the town of New Liskeard, in the Province of Ontario, Dominion of Canada, have invented certain neiv and useful Improven'ients in Table Locks, of Which the following is a specification.

This inivention relates to improvements in table locks and more particularly to locks foil extension tables.

The objeots of the invention are to provide a simple, economical and effective device of this kind for extension tables Whereby on the table being e-tended to receive one or more leaves, the whole may be securely held and locked together and as readily released or unlocked When desired.

lVith the foregoing and other objects in view, the invention consists essentially of a guiding member suitably notched to fit on one section of an extension table and a locking member ada-pted to slidably engage the guide member to fit on the other table seotion, and means for operating the looking member.

Referringto the drawings, in Which like characters of reference indicate corresponding parts in each tigure.

Figure 1 is a side elevation of an extension table fit-ted With my invention.

Figure 2 is a perspective -vieW of the table lock detached from the table, and

Fivure 3 is a cross sectional view on 33, of Figure 2.

In the drawings;

A. is tlie lock or device as a Whole and B is an ordinary extension tabl-e comprising` two sections C and D, With the lock A fitted thereon. This lock A comprises, as here illustrated, an lshaped metal strip or guide ieinber includinga side 11 and base 12 forine-d With a guiding' edge 13 and designed to be litted and fiX-edly secured on the side of one of the table sections and to be securely held there by suitable retainingr means through the orifice 14:. 15 are notches suitably spaced to correspond With the Width of the extra table leaves and adapted to engage With the looking member. This meinber is securely fitted on the other Section C of the table A and comprises a looking bar 16 forme-d With a loope-d end 17 adapted line the notches 15.

to engage and lock With the notches 15. The other end of the looking bar 16 is formed With a bend adjacent to the end thereof while the end itself is bent inwardly to engage With a crank member 18 provided With a handle 18EL and pivotally mounted on a plate 19 in turn mounted on the table Section C. 20 is an intermediate support for the bar 16 between the operating en-d and the guide member 10 and is preferably mounted on the same Section of the extension table as the looking member. The member 20 is provided With a slot for receiving the rod 16 therethrough and made suificiently larger-than the rod to permit vertical movem-ent of the latter therein. 21 is the bend previously referred to in the bar 16 Whereby in combination With the operating crank 18 and the guide 20, the looking end 17 of the looking bar 16 is operated to lock With 22 is a combined guard and guide plate fixedly secured on the bar 16 and designed to slidably engage With the ridge 13 on a guide member 10 to retain the bar in place on said guide member.

From the foregoing, it Will be evident that upon the movem-ent of the crank 18 the bar 16 Will be shifted to engage or disengage the hook en-d 17 With the slots 15 to lock or unlock the bar 16 dependent upon the direction of crank movement, the notches 15 be-l ing spaced preferably according to the Width of the leaves of the table.

If two leaves are put in, the looking bar engaging point Will be opposite the second notch to b-e there locked by the operating crank handle.

As many changes could be made in the above construction, and' many apparently Widely different embodiments of my invention, Within the scope of the claim, constructed Without departing from the spirit or scope thereof, it is intended that all matter contained in the accompanying specification and drawings shall be interpreted as illustrative and not in a limiting sense.

That I olaim as my invention is:

A table lock of the character described, comprising a plate adapted to be attached to one Section of the table and pres-enting a horizontal portion formed With a series of longitudinally spaced notches, a vcrank pivoted at one end to another Section of the table, n looking rod rigidly seoured att one end to an internedate portion of the orank and equipped at its opposite end With means adapted to engage and disengage the notches of the said plate upon tilting of the looking rod in response to pivotal movement of the Crank and a braoket provided With a slot loosely receiving the intermedate portion of the rod therethrough, said braclrets serving to limit upward and downvmrd tilting 10 of the rod.

In Wtness Whereof I have hereunto set my hand in the presence of two Witnesses.
